History is *a* science among others. It has its own methods but shares the same naturalistic outlook as any science. Most of the historians of antiquity prefaced their writing by denouncing any recourse to supernatural events (like gods interventions in human affairs). They did so precisely because they were *not* trying to write mythology but a realistic, naturalistic history of events, and they wanted their readers to understand the difference. 

As a matter of principle, as it was conceived millenaries ago to be a different discourse than mythology, and as currently practiced by modern historians, history is therefore not in the business of confirming miracles. On the contrary, one of its tasks is to demystify the past.
